摘要： A storage controller may be configured to assess the reliability of a solid-state storage medium. The storage controller may be further configured to project, forecast, and/or estimate storage reliability at a future time. The projection may be based on a currently reliability metric of the storage and a reliability model. The portions or sections of the solid-state storage media may be retired in response the projected reliability metric failing to satisfy a reliability threshold. The reliability threshold may be based on data correction and/or reconstruction characteristics. The projected reliability metrics of a plurality of erase blocks of a storage division may be combined, and one or more of the erase blocks may be retired in response to determining that the combined reliability metric projection fails to satisfy the reliability threshold.

摘要： A storage module is configured to determine a health metric of a storage division of a solid-state storage medium. The health metric may comprise a combination of factors, including, but not limited to: wear level, performance (e.g., program time, erase time, and the like), error rate, and the like. A wear level module may configure storage operations to reduce the wear rate of storage divisions having poor health metrics and/or heath metrics that are degrading more quickly than other storage divisions. Reducing wear rate may include deferring grooming operations, delaying use for storage operations, temporarily retiring the storage division, or the like. Storage divisions may be brought back into service at normal use rates in response determining that other portions of the storage media have been worn to the point that they exhibit similar health and/or reliability characteristics.

摘要： An apparatus, system, and method are disclosed for implementing conditional storage operations. Storage clients access and allocate portions of an address space of a non-volatile storage device. A conditional storage request is provided, which causes data to be stored to the non-volatile storage device on the condition that the address space of the device can satisfy the entire request. If only a portion of the request can be satisfied, the conditional storage request may be deferred or fail. An atomic storage request is provided, which may comprise one or more storage operations. The atomic storage request succeeds if all of the one or more storage operations are complete successfully. If one or more of the storage operations fails, the atomic storage request is invalidated, which may comprise deallocating logical identifiers of the request and/or invalidating data on the non-volatile storage device pertaining to the request.

摘要： Apparatuses, systems, and methods are disclosed for reconfiguring an array of storage elements. A storage element error module is configured to determine that one or more storage elements in an array of storage elements are in error. An array of storage elements stores a first ECC block and first parity data generated from the first ECC block. A data reconfiguration module is configured to generate a second ECC block comprising at least a portion of data of a first ECC block. A new configuration storage module is configured to store a second ECC block and associated second parity data on fewer storage elements than a number of storage elements in an array.
